SOFA-BED.

SPECIFICATION forming part of Letters Patent No. 324,490, dated August 18, 1885.

Application filed July 24, 1883.

.To all whom t may concern.-

Be it known that I, Aivios ScHRocK, of 'Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sofa-Beds; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to that class of sofabeds having horizontal upholstered surface or seat and a hinged back adapted to be lowered into the same horizont-al plane with the seat to form a bed.

The objects of the invention are to provide an improved construction in the supportinglegs for the hinged back, in locking devices for holding the said back in a vertical position, and in the frame and the upholstered covering of the frame.

To these ends the invention consists in the matters hereinafter described,and pointed out in the claims. Y

In the accompanying drawings, Figure 1 is a perspective View of the article in the form of a sofa. Fig. 2 is a perspective view of the lsame when in bed form. Fig. 3 is a perspec- 'tive view of the sofa-frame, with the upholstering removed. Fig. et is a rear elevation of the same. Fig. 5 is a vertical transverse section taken upon the line :v x of Fig. L

A sofa-bed embodying my invention, as `shown in the drawings, consists in its general features of a main horizontal seat portion, A, a back, B, secured by hinges to the rear edge of the seat A, and an inclined head-rest, C.

The back B is constructed to fold down into 'the same horizontal plane with the seat, so as,

to form a bed, in a Well-known manner.`

As shown in the drawings, the head-rest C is made in two parts, C and C2, the lower part, `C', being stationary and secured to the sofaframe, and the upper portion, C2, being attached at its rear edge to the rear edge of the p'art C', so as to form the upper surface of the inclined head-rest C of the sofa,as shown in Fig. 1 0r to open and form with the part C a suitable bolster extending the entire width of the parts A and B when the article is in the form of a bed, as shown in Fig. 2.

The main frame of the part A, as shown in the drawings, consistsof two horizontal lside pieces or rails, A', supported upon suitable (No model.)

legs, a, and two cross-pieces, D and D, connecting thesaid rails, the cross-piece D at the foot of the sofa being attached to the ends of the rails, and the cross-piece D being secured thereto at a point adjacent to the head-rest.

The ends a of the rails A at the head of the frame form a support for the head-rest C, and for this purpose are usually extended upward in curved or other form, as indicated.

The frame 'of the folding back B of the sofa consists of alongitudinal rail, E, and two end pieces, Dl D3, rigidly secured to said rails at their upper or outer ends, and connected at their inner ends with the rear ends of the cross-pieces D and D', respectively, by means of hinges d. Being arranged end to end with the cross-pieces D and D', when folded down into a horizontal position, as shown in Fig. 3, said end pieces D2 and Da form continuations of the said cross-pieces, and, together with the latter,compose the end rails of the bed-frame, having their upper surfaces elevated above the intervening portions of the longitudinal rails A, A', and E. To these elevated end rails are secured the ends of a longitudinally-elastic woven-wire fabric` I, under suitable tension, as indicated in Fig. 3. The stuffed covering or cushion of the sofa-back is secured directly to or upon this Woven-wire fabric, and the latter forms an elastic or yielding support for said cushion, dispensing with the use of spiral or other springs for this purpose. Vhen the article is in sofa-form, both back and seat are therefore equally yielding, and when extended in bed form theyT present t-he usual characteristic of a woven-wire mattress with the advantage of a permanently-secured cushioned covering thereon. By using elastic wire fabric instead of the usual springs as a foundation for or the supporting part of the upholstering the surfaces are extremely soft and yielding,equaling, 9

in this respect, the deepest upholstering as ordinarily constructed, while at the saine time the fabric and its cushioned covering are together so thin that they may be readily folded in the line d d when the back is elevated. This construction is also obviously very light, so that, while the sofa has a desirably heavy and luxurious appearance, it is readily'moved from place to place, and the back may be raised and lowered with'little labor. The upholstering or cover is extended over the front edge of the seat and the upper or rear edge of the back, and is connected with the adja- IOO cent parts of the frame in the manner indicated in Figs. 1 and 2, in order to present a desirable appearance.

The hinged back B of the sofa is supported when in horizontal position by nieans of folding legs F, said legs being composed of metal rods, which are connected at right angles to the ends of the rods or bolts F', heldin sleeves G, attached tothe end pieces, D2 and Dief the frame of the said back B. The bolts F are arranged in position parallel with the end pieces, D2 and D3, and are constructed to rotate in the sleeves G thereon, so that t-he legs F, attached thereto, may be folded inwardly against the sofa-back. The bolts F are also constructed to slide longitudinally in the said sleeves, so that when the sofa-back is placed in a vertical position, as illustrated in Fig. 5, the ends of `the said rods may enter vertical apertures in lugs H', secured upon the rear face of the rear rail, A', of the sofa-frame, and thereby retain the sofabaek in its vertical position. The sleeves G and lugs H are lnade of considerable length; so as to afford sufficient bearing upon the bolts F to hohl the sofa-back .rigidly in its vertical position, the said rods being inade of sufficient strength to withstand any strain that may come upon theln. The sleeves G, in which the bolts F are held, are preferably provided with spiral slots g, in which are inserted pins f, secured in the said rods F, which pins travel in and are guided by said slots when the legs F are moved. rlhe spiral slots g are extended through an are of about onefonrth ofa eircle, and are extended lengthwise of the sleeve a distance equal to the longitudinal 1noVenient of the bolts F', the said slots being so arranged that when the legs are turned out wardly and in position to support the back B the pins f will be in the portion of the slots remote from the rail A and the bolts F will be drawn back, and when the legs are folded inwardly into the plane of the said back portion, as shown in Fig. 4, the action of the pins in the slots will nieve the said bolts longitudinally and into position for the engageinent with the lugs ll. By this construction the back is locked automatically in its vertical position by the operation of folding the supportinglegs F inwardly when the sofa is raised. lhe end pieces, I)l and D", to which the sleeves Garesecured, are, as shown, hinged at their -npper sides to the rear side of the rear rail, A, of the sofa-frame, and the said sleeves are secured upon the inner faces of said end pieces, so that when advanced the bolt-rods F will pass to the rear of the said rail, and will be in position to enter the boltapertures in the lugs H, attached thereto, as shown in Fig. 5, in which figure the frame of the part B is indicated in its horizontal position by dotted lines.

The upper end of the portion of the bed formed by the folding back B consists, as before stated, of the portion GL of the headrest C, the frame C of said portion (l2 being connected with the stationary frame C of the part C by means of hinges c, as shown in Fig. 3.

No special means are usually necessary for supporting the rear end of the folding headpiece C2, the lower edge of the said piece overlapping the upper edge of the folding back sufficiently to retain it in position. A suitable stop or rest, d', may, however, be secured to the cross-piece D", against which the frame C1 will rest when folded back, said stop being shown in Fig. 4.

The wire fabric mentioned may be an elastic woven fabric, such as is used in the construction of woven-wire mattresses or other elastic wire fabric suitable for the purpose.

I elaiin as 1ny inventionl. A folding sofa-bed frame having its seat and back portions provided with an upholstering consisting of an elastic wire fabric stretched over and secured at its ends to the folding frame, and a stuffed covering applied upon and secured to the said wire fabric, substantiall y as described.
